YVR is a great looking airport, at least inside. Lots of great artwork. DEN is in a great location. YYC is undergoing a lot of renovation, but being able to see the Canadian Rockies while you wait for a plane is worth the wait.

For us that have been to Koh Samui (USM), Thailand, I'll guess there is no doubt that this little airport with its small open bungalows is the best looking airport in the world, and in my opinion an airport that you shouldn't hesitate to visit if you get the chanse.

Jeff,
MCO is very nice inside but it can be confusing. Having opposite ends of the same building called Terminal A and Terminal B is not a great idea. An example of the confusion it can cause happened to me a few months ago. I was supposed to pick up someone who was returning a rental car to the Alamo drop-off location. What neither of us knew was that Alamo (and other rental companies) have drop off points at both ends of the building. My friend took the car to the Terminal A end, while I followed the first signs I saw, which happened to be Terminal B. The consequens was that we spent the best part of an hour patiently waiting for each other. I wasn't worried as I knew my friend was never on time for anything . He finally made inquiries and we eventually got together.
I've had a similar experience meeting flights - with the arrivals board showing a flight coming to a Terminal A gate, and then the plane actually arriving at Terminal B.

I agree with those of you who voted Paris CDG - the architecture there and the spaciousness is absolutely breath-taking. Dulles Airport in DC is also really nice - they have a huge model airplane store in the main terminal. Amsterdam Schipol, Munich Franz Josef Strauss, Zurich-Kloten, and London Heathrow are also really nice. MUC and ZRH are in nice areas, and AMS and LHR have a lot to do. Osaka Kansai, KIX also has very nice architecture like CDG. I also liked Hong Kong's old airport, Kai Tak, located in an awesome place. And, no doubt, my hometown airport - LAX - is cool to! It's great at night, when you are entering it. You are greeted by fluorescent neon poles that stick up in the air and silver-colored blocks that say "LAX"...it's really nice.

HNL is a really awesome airport. Because it was built with widebodies in mind, the terminals are large and spacious, so they don't feel cramped. Many areas are also open air and the redesgned entrances to the check-in areas and the gardens are really beautiful. It's the only airport i know of that doesn't have white walls/ceilings and blue/gray carpet. A+ in my book!

No problem acknowledging Vancouver International with its spectacular three dimensional artwork and water features. You descend the main staircase into entrance customs over rolling river rapids. I've never seen anything like that.

Washington National's new terminal space, constructed for its B, C, and D gates, is also spectacular with soaring anodized metal arches, handset marble floor medallions, and commissioned artwork. And the original 1930s terminal building, attached to the separate 'A' terminal and gates, has had much of its art-deco interior restored. The 'A' terminal and gates, redone in the 70s, do need sprucing up.

Penguinflies writes, "No one has really said the midfield terminal at DTW. It is beautiful."

That is so. It's called the McNamara terminal (and where Spirit Airline hubs is called the Berry terminal). I remember going through McNamara the first week is was open awed by nearly a mile of floor-to-ceiling glass. The huge black granite water feature at the terminal's midpoint kept getting clogged up with coins people would throw into it and overflowing onto the floor. Now the fountain's drains are regularly sifted and the coinage turned over to charity. I've watched people miss their connections riding the (almost totally silent) tram back and forth. But DTW has both a Marriott and a Westin for those who must stay overnight. Talk about compound luxury.
